All 298 people as you know on board killed. We'll go back to ABC's terry Moran in kiev and he has the very latest for us. Good morning, terry. Reporter: Good morning, robin. Fast-breaking developments on this story this morning. The team of international investigators en route to the crash scene, there are now questions about whether the rebels who control that scene will allow them access to it and the rebels are changing their story. Yesterday they said they had the black boxes, they'd found those. The Ukrainian president is pointing the finger directly at the separatists and saying this is not a disaster or an accident, it's an act of terrorism but those rebels are saying it was Ukrainian forces who shot down the plane and the Russian side in rebel-held eastern Ukraine and this, the moment of impact. The huge Boeing 777 slamming into the ground sending up plumes of smoke and those white streak, pieces of the plane raining down. It was 4:20 P.M. Local time. Traveling at 33,000 feet crossing over war-torn Ukraine, the plane is apparently struck by a surface-to-air missile. It loses contact with ground control some 30 miles from the Russian border crashing into rebel-held territory. Authorities say no distress call came from the pilot. Our reporter John wendle was on the scene amid the carnage. Reporter: We found part of the tail fuselage. There is a body next to it. It is a very grim scene that we're seeing here. Reporter: The bodies rained down from the sky, witnesses said. Passports, boarding passes, belongings falling with them. Relics of 298 lives including three newborns. As the wreckage smoldered back in the U.S. Talk quickly turned to terrorism. Shot down, not an accident. Blown out of the sky. Reporter: The question this morning, who fired that missile? If that's in fact what brought down the plane. The Ukrainian president is pointing the finger directly at the separatists. He's saying this is not a disaster or an accident, it's an act of terrorism. But those rebels are saying it was Ukrainian forces who shot down the plane and the Russian president, Vladimir Putin, is saying that the Ukrainian government is responsible. This atrocity being sucked into the war of words that is raging here alongside the civil war in Ukraine.
